Abstract
Dabigatran, an anticoagulant, may increase the risk of bleeding in patients with dysfibrinogenemia because of coagulation irregularities, especially at high doses. Cranial Magnetic Resonance Imaging (MRI) and Magnetic Resonance Venography (MRV) were used in the diagnosis of venous sinus thromboembolism in a 42-year-old woman with hereditary dysfibrinogenemia, as documented in our case report. Cranial MRI suggested thrombosis in the venous sinuses, which was confirmed by MRV as thromboses in the superior sagittal, straight, left transverse, and sigmoid sinuses. Instead of the usual fixed-dose, we gave the patient dabigatran based on how the coagulation indicators changed. Forty-six days after treatment, the patient's clinical symptoms had largely resolved. Follow-up cranial MR showed that most of the venous sinus thromboses had disappeared, with some mural thrombi still present in the superior sagittal sinus and left sigmoid sinus. In this report, we optimized the dabigatran regimen adjusted to thrombin time, ensuring efficacy with low bleeding risk.
期刊介绍:
British Journal of Hospital Medicine was established in 1966, and is still true to its origins: a monthly, peer-reviewed, multidisciplinary review journal for hospital doctors and doctors in training.
The journal publishes an authoritative mix of clinical reviews, education and training updates, quality improvement projects and case reports, and book reviews from recognized leaders in the profession. The Core Training for Doctors section provides clinical information in an easily accessible format for doctors in training.
British Journal of Hospital Medicine is an invaluable resource for hospital doctors at all stages of their career.
The journal is indexed on Medline, CINAHL, the Sociedad Iberoamericana de Información Científica and Scopus.
